Infraorbital Groove and Canal
Infraorbital Groove and Canal
The infraorbital nerve and blood vessels pass through this groove and canal, located in the maxilla bone.
Which bone doesn't form orbital margin?
Which bone doesn't form orbital margin?
The sphenoid bone, located deep within the skull, does not directly contribute to the bony rim of the eye socket.
Nasolacrimal Canal
Nasolacrimal Canal
The nasolacrimal duct, responsible for tear drainage, passes through this opening in the lacrimal bone.
